Question

Find the exact value of the radical expression in simplest form.
√169− √50− √8

Answer 1

Try to split the terms in the square roots into components of which you know the square root. Remember:
\[\sqrt{ab}=\sqrt{b}\sqrt{a}\]

Answer 2

We can do the last term as an example:
Lets say
\[8=2*4\]
Then:
\[\sqrt{2*4}=\sqrt{4}*\sqrt{2} = 2*\sqrt{2}\]

Answer 3

so you do that for every number and then put them together?
